6. Direct encoder with position tracking for the measuring gearbox:
v = (p0412 * p2506) / p2576
Note:
With position tracking, it is recommended that p0412 and p2721 are changed
See also: p0412 (Measuring gearbox, rotary absolute gearbox, revolutions, virtual), p0432 (Gearbox factor, encoder
revolutions), p0433 (Gearbox factor, motor/load revolutions), p2504 (LR motor/load motor revolutions), p2505 (LR
motor/load motor revolutions), p2506 (LR length unit LU per load revolution), p2576 (EPOS modulo correction, mod-
ulo range), p2721 (Load gearbox, rotary absolute gearbox, revolutions, virtual)
Reaction upon A: NONE
Acknowl. upon A: NONE
F07443 (A) LR: Reference point coordinate not in the permissible range
Drive object: SERVO, VECTOR
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The reference point coordinate received when adjusting the encoder via connector input CI:p2599 lies outside the
half of the encoder range and cannot be set as actual axis position.
Fault value (r0949, interpret decimal):
Limit value (absolute value) for the reference point coordinate.
Remedy: Set the reference point coordinate less than the limit value specified in the fault value.
See also: p2598 (EPOS reference point coordinate, signal source), p2599 (EPOS reference point coordinate value)
Reaction upon A: NONE
Acknowl. upon A: NONE
F07446 (A) Load gearbox: Position tracking cannot be reset
Drive object: SERVO, VECTOR
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The position tracking cannot be reset.
Remedy:
Reaction upon A: NONE
Acknowl. upon A: NONE
F07447 Load gearbox: Position tracking, maximum actual value exceeded
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: When the position tracking of the load gearbox is configured, the drive/encoder (motor encoder) identifies a maxi-
mum possible absolute position actual value (r2723) that can no longer be represented within 32 bits.
Maximum value: p0408 * p2721 * 2^p0419
See also: p0408 (Rotary encoder pulse No.), p0419 (Fine resolution absolute value Gx_XIST2 (in bits)), p2721
(Load gearbox, rotary absolute gearbox, revolutions, virtual)
Remedy: - reduce the fine resolution (p0419).
- reduce the multiturn resolution (p2721).
See also: p0419 (Fine resolution absolute value Gx_XIST2 (in bits)), p2721 (Load gearbox, rotary absolute gearbox,
revolutions, virtual)
F07448 (A) Load gearbox: Position tracking, linear axis has exceeded the maximum range
Drive object: SERVO, VECTOR
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: For a configured linear axis/no modulo axis, the drive/encoder has exceeded the maximum possible traversing
range.
For the configured linear axis, the maximum traversing range is defined to be 64x (+/- 32x) of p0421. It should be
read in p2721 and interpreted as the number of load revolutions.
